TCM calibration for the C8 Corvette dual-clutch transmission — E-Ray, Z06 and ZR1.
Johnson Tuning is the only source for properly tuned TCM high-pressure maps, developed with our own proprietary software. The calibration covers high clutch pressure, corrected line pressure, adjusted shift points and launch control.
Before you order
Select your model and contact Johnson Tuning to confirm flash-point requirements.
HP Tuners requirements
For supported E-Ray 2024–2026, Z06 2023–2026 and ZR1 2025–2026 applications, the T46 transmission controller requires 6 Universal Credits. The original TCM must complete HP Tuners’ separate T46 Global B upgrade before transmission tuning. MPVI4 and current VCM Suite are required. Confirm the available model option and your controller before ordering.
This TCM service does not include engine calibration. If engine tuning is also ordered, its ECM upgrade and licensing are separate: E99 E-Ray engine controllers use 8 credits; E68 Z06/ZR1 engine controllers use 10 (14 or 16 total with TCM licensing, respectively).

Shop MPVI4 and available credit bundles. The store offers 0, 2 or 4 credits with the interface; contact Johnson Tuning to arrange any remaining credits. Hardware, credits and controller upgrade services are separate from the remote tune. Confirm your VIN, model year, controller/OS and transmission with Johnson Tuning and HP Tuners’ current supported vehicle list before ordering.
